Has anyone tried the new Robbys's Restrictor that just came out?

I heard about it from my Pro Shop months ago when he went on a tour of the Ebonite plant. He was impressed with how well it stopped your hand from overturning without having to wear any type of glove or wrist support. If my wrist heals, I might look into this to help train me not to overturn on the ball. Here's the link to it on their website:
